I know the Sox had to put Nieto on the OD roster if they wanted to keep him, but what are the rules from here? Could they send him down in a few weeks if they wanted to?

He has to stay on the 25-man roster for the entire season or they have to offer him back to the Nationals. If he survives this season, he's no longer subject to Rule V Draft rules and can be sent to the minors or traded as the Sox see fit.

I'm glad they've added Nieto- I'm also glad for the side benefit of adding him which was cutting Phegley- and establishing a higher bar of competition and performance- part of the culture change Hahn is implementing.

Hope he improves the position but I am not ready to write off Phegley just yet.

The bar can't get any lower w Flowers. He is probably the overall worst hitting catcher in baseball. Remember he has struck out almost 40% of his ML at bats.
